Directions

Follow the step-by-step instructions below to teach the lesson.

Progress to the next lesson when children master the current lesson.

Value mastery over speed of progression.

Steps

STEP 1

Have children recite and solve each equation listed below.

STEP 2

Have children copy on paper the equations listed below and their solutions.

EQUATIONS

• 8+1 or 1+8= ; therefore 9-1= ; 9-8=
• 7+2 or 2+7= ; therefore 9-2= ; 9-7=
• 6+3 or 3+6= ; therefore 9-3= ; 9-6=
• 5+4 or 4+5= ; therefore 9-4= ; 9-5=

Repeat this lesson every day until children can easily recite and write the equations and their solutions.
